Complete sequence of muTNFR-Fc. The sequence for murine TNFR (amino acids 23 to 258) was directly fused to the murine
Fc fragment (amino acids 98 to 324), containing the hinge, CH2 and CH3 regions. At
the N-terminus a signal sequence (SS) was added. By HindIII and NotI double digest the insert was included into the mammalian cell-expression vector
pcDNA3.1(+).
